如何强制依赖项包含具有特定版本号的工件

Question

尝试使用 maven 构建 GWT 项目时出现此错误：

您的项目声明对 gwt-user 2.6.0 的依赖。这个插件是 至少为 gwt 2.7.0 版设计

我发现 gwt-user 2.6.0 是使用 com.google.gwt.eventbinder 下载的。 如何强制 com.google.gwt.eventbinder 使用 gwt-user 2.7.0 而不是 2.6.0？

奇怪的是，在我执行 'git pull' 之前构建工作。

这是我的 pom.xml

解决方案 1

问题是 eventbinder 依赖于 gwt-user 工件。它默认使用2.6.0，你可以通过这个命令看到它。

mvn dependency:tree

如果你把这个依赖块添加到你的 pom 中；

<dependency>
   <groupId>com.google.gwt</groupId>
   <artifactId>gwt-user</artifactId>
   <version>2.7.0</version>
</dependency>

它看起来像这样......

这意味着您的项目将一直使用 gwt-user 2.7.0，我还没有测试过版本兼容性是否一切正常，或者您的问题将得到解决..

解决方案 2 感谢@Thomas Broyer 的评论，我们可以强制 eventbinder 使用 2.7.0 gwt-user 或任何 gwt 依赖项。如果我们只是将这个依赖管理添加到我们的 pom 中

<dependencyManagement>
 <dependencies>
  <dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt</artifactId>
    <version>2.7.0</version>
    <type>pom</type>
    <scope>import</scope>
  </dependency>
 </dependencies>
</dependencyManagement>

结果：
